Building having a room of cell-like design arranged in its interior

ABSTRACT

Building having at least one inner room in which at least one further room of approximately cell-like design is arranged, wherein the floor region ( 28 ) of the cell-like room ( 21 ) separated from the building is set apart from a cell-supporting surface ( 10, 12 ) of the building in a sound-isolating manner by at least one spacer element ( 30 ) made of sound-insulating material or materials.

BACKGROUND OF THE INVENTION

The invention relates to a building having at least one inner room in which at least one further room of cell-like design is arranged.

The goal set by the inventor is to design combinations of this type such as to produce sound-protected examination rooms at the premises of ear, nose and throat doctors or in specialist acoustic centers, or a soundproof room for operating personnel in industrial production halls. It is also intended to make possible the production of soundproof rooms which may be employed in halls containing production machines so that the surrounding room is protected from noise. Another intention is to be able to use such combinations to set up meditation rooms in private houses or in airports and hotels.

SUMMARY OF THE INVENTION

This object is achieved by the teaching of the independent claims; the subclaims specify advantageous developments. Furthermore, any combination of at least two of the features disclosed in the description, the drawing and/or the claims comes within the scope of the invention. Where designated ranges are specified, values situated within the stated limits are also intended to be disclosed, and to be able to be used at will, as limit values.

According to the invention, the floor region of the cell-like space separated from the building is set apart from a cell-supporting surface of the building in a sound-isolating manner by means of at least one spacer element made of sound-insulating material or materials; the spacer element is intended to be formed from a dimensionally stable sound-insulating material, for example to be configured as a rubber bearing.

It has proved advantageous to arrange the strip-like or panel-like spacer element on the underside of the floor structure of the cell housing enclosing the cell-like room, approximately at the corners of said housing.

A frame, preferably a flat frame, made of metal material and intended for connection to spacer elements is advantageously mounted on the underside of the floor structure; the free height of these spacer elements is intended to determine the distance between the cell-supporting surface of the building and the underside of the floor structure of the cell-like room or of the room-enclosing cell housing. The width of the spacer element is preferably less than the width of said flat frame, with the result that the spacer elements can be connected with full-surface contact to this frame. The frame may consist of a lightweight metal alloy, but may also be configured as a flat steel frame.

In another embodiment, it is intended for the spacer elements to be able to be distributed at a distance from one another on the underside of the floor structure.

It is provided within the scope of the invention that the floor structure of the cell housing comprises a number of layers, of which the lowermost is configured as a rigid base panel, in particular as a sheathing panel; for the purpose of blocking off sound, the floor structure is intended to comprise at least one plasterboard panel which is additionally spanned by a carpet-like covering.

According to the invention, cell walls are seated on the base panel, these cell walls providing a soundproofing structure and thus protecting the inner room. To this end, the cell walls are each intended to be provided, on either side of a gap, with insulating panels which may contain a metal upright as holding element which is surrounded by insulating material. Moreover, a ceiling panel is seated on the walls, the structure of which ceiling panel corresponds approximately to that of the walls.

The room depth, room width and room height of the acoustic cell according to the invention can be chosen at will. Moreover, it is not crucial for windows to be installed in the room-enclosing surfaces. The crucial idea is a room-in-room system which is acoustically separated from all surrounding architectural and structural components. This is achieved by virtue of the fact that the acoustic cell or the acoustic room does not allow any connection to result with the surrounding walls, floor and ceiling, and its boundaries consist of materials which do not transmit sound. Here, this material can be inserted as a surface or at points between the acoustic room and floor. The latter thus stands on non-sound-transmitting material and is acoustically isolated.

DETAILED DESCRIPTION

Two floors 10, 10 _(a) of a building, which is not shown in any further detail, extend parallel and at a vertical distance from one another. The lower floor 10 bears a multi-layered floor unit 11 which is covered by a covering layer 12. A false ceiling 16 is suspended from the upper floor 10 _(a), thereby forming a ceiling space 15 which, inter alia, contains pipes 14 at a center spacing a from the floor 10 _(a) of, in this case, 10 cm, this false ceiling being at a spacing b from the floor of, in this case, 19 cm and determining a room height h of, for example, 2600 mm. On the left-hand side, at a spacing b₁ of 330 mm from the floor 10 _(a), can be seen a suspended ceiling 17 which terminates at a horizontal spacing c of approximately 100 mm from a vertical intermediate wall 18 to form an alcove-like room section for lights 19.

An outer surface of a cell housing or of an acoustic cell 20, which, as described below, is acoustically isolated from all surrounding architectural and structural components, extends at a horizontal spacing c₁ of, in this case, 120 mm from the edge 17 _(k) of the suspended ceiling 17. In this acoustic cell 20, a front and rear wall 34, 36, which are connected by side walls 38 as shown in FIG. 3, project vertically from a heavy sheathing panel 22 having a thickness e of 25 mm. Upon said base panel or shutter panel 22 are situated a wooden fiberboard 23 having a thickness e₁ of 10 mm and a plasterboard panel 24 having a thickness e₂ of 23 mm as a bearing surface for a carpet covering 25 having a thickness e₃ of approximately 10 mm; these layers 22, 24, 25, supplemented by a flat steel frame 26 having a thickness e₄ of 10 mm and a width g of 100 mm, form the floor structure 28 with an overall thickness f of almost 70 mm. Instead of said flat steel frame 26 it is also possible to use a frame 26 formed from a different metal material.

The flat steel frame 26 of the floor structure 28 is employed as a holding means for sound-isolating bearing members 30 made of sound-insulating material, in particular for rubber bearing members 30 which bring about sound isolation and which can be mounted in various configurations, for example as strips or panels of various design. These rubber bearing members 30 determine, by way of their height y, the spacing h₁—of 93 mm in this case—between the surface of the covering layer 12 of the floor unit 11 of the floor 10 on the one hand and the surface of the carpet covering 25 in the acoustic cell 20 on the other hand, and also the gap spacing.

On either side of a metal upright 40 having a width g₁ of 100 mm and comprising an insulating material 42, the walls 34, 36, 38 each have insulating panels 44, 46 with an overall width f₁ of 25 mm; the surface of the inner insulating panel 46 that faces the interior 21 of the acoustic cell 20 is provided with a carpet covering 25 _(a) whose thickness e₅ also amounts to approximately 10 mm. Close to the lower edge of the outer insulating panel 44 forming the outer surface of the acoustic cell 20, a concealed joint with a height of 1.5 mm is formed, at 48, in said insulating panel.

The carpet covering 25 _(a) in 1 terminates at the underside 49 of a ceiling panel 50 which spans the acoustic cell 20 and which bears on the walls 34, 36, 38, the spacing h₂ from the inner surface of said ceiling panel to the inner surface of the floor 10 _(a) being approximately 360 mm. In FIG. 2, the upper edge of the carpet covering 25 _(a) is at a spacing h₃ from the underside 49 of the ceiling panel 50 and serves as a holder for an inner upper panel 46 _(a), which is thus at a spacing from the ceiling panel 50. Its longitudinal section is also shown by the metal upright 40 and the outer insulating panel pair 44/46; toward the interior 21 of the acoustic cell 20 is provided only one insulating panel 46 which, as stated, is at a spacing h₃ from the metal upright 40 of the ceiling panel 50 in FIG. 2.

FIG. 3 indicates the ground plan of an acoustic cell 20 having an outer length i of 500 cm and a double width n of 310 cm. The outer height k corresponds to the acoustic cell 20 and here amounts to 252 cm. In a strip-like opening 37, the rear wall 36 contains a window 52 having a length i₁ of approximately 300 cm and a low height n₁ of 50 cm. A door 54 having a width i₂ of 110 cm is fitted off-center in an opening 37 in the front wall 34.

The ceiling plan in FIG. 7 between the front wall and rear wall 34, 36, having an inner free length q of 470 cm, and the side walls 38, having an inner free length q₁ of 280 cm, shows a construction network composed of squares 56 having a side length t of 60 cm between continuous border strips 58 and 58 a having a width z of 20 cm and z₁ of 25 cm, respectively.
